Ukraine's navy chief has announced that he has switched allegiance to the pro-Russian authorities of the flashpoint peninsula of Crimea.

The move comes a day after Denis Berezovsky was appointed to the post by interim leader Oleksandr Turchynov.

Mr Berezovsky said in a televised statement that he "swears allegiance to the residents of the Autonomous Republic of Crimea".
